Abstract

A computer keyboard includes a keyboard frame seat, playing keys, function keys, contact components, circuit boards, cables and a plug. The playing keys are the keys of a piano. The utility model can simulate the playing of an electric piano by computer software and hardware and has a powerful function and low cost when combined with a computer.

Description

A kind of computor-keyboard

The utility model relates to a kind of computor-keyboard.

Along with further developing of computer technology, powerful soft, hardware supported have been arranged, computer can be simulated the situation in the various reality.People can utilize computer to simulate the operation of mellotron on keyboard now, but the distribution of the button of standard computor-keyboard is not to design for the simulation electronic qin, utilizes standard computor-keyboard simulation electronic qin to bring great inconvenience to the operator.Computer software has powerful editting function, the melody of playing can be noted and be used for revising, resetting or the like, so also there is the mellotron product to have the interface that connects with computer on the market, but, this mellotron all is an expensive goods, its price also is that domestic consumer is difficult to bear, and mellotron is with after computer connects, and computer software can utilize sound card, audio amplifier to realize the vocal function that hard wave table, audio frequency combiner circuit, power amplifier, the loudspeaker of mellotron inside can reach fully; In a sense, the internal circuit of existing mellotron can realize on computers, and with after computer connects, this part expensive equipment is the heavy overlapping investment of consumer with mellotron.

The purpose of this utility model is to provide a kind of computor-keyboard that is convenient for people to the simulated operation mellotron.

For achieving the above object, the utility model is by the following technical solutions:

A kind of computor-keyboard, comprise keyboard skeleton frame, function button, performance button, contact element, surface-mounted integrated circuit, connection line cable and plug, function button, performance button are installed on the keyboard skeleton frame, contact element is installed between button and surface-mounted integrated circuit, connection line cable one end links to each other with surface-mounted integrated circuit, and described performance button is a key.Like this, just can utilize soft, the hardware of computer to realize the operation of simulation electronic qin.Compare with the standard computor-keyboard, can be more convenient in the operation; Compare with existing mellotron, cost greatly reduces, for mellotron has very important effect at family universal.The utility model comes down to utilize the button of standard electronic qin and computer is soft, combination of hardware realizes the operation of simulation electronic qin, and is with low cost with regard to key, and the power support of software has been arranged, and the utility model is had wide practical use.

Above-mentioned computor-keyboard, it plays key is 49 keys that comprise two kinds of keys of black and white.This is a kind of simple and easy keyboard, and the distribution of its keyboard is consistent with existing 49 key portable electronic piano key boards, comprises black and white comprising four note word groups that 49 keys of two kinds of keys form (C of big word group being to the C of small character group ³).

Above-mentioned computor-keyboard, it plays key is 61 keys that comprise two kinds of keys of black and white, the distribution of its keyboard is consistent with existing 61 key portable electronic piano key boards, comprises black and white comprising five note word groups that 61 keys of two kinds of keys form (C of big word group being to the C of small character group ⁴).

Above-mentioned computor-keyboard, it plays key is the keyboard of one deck at least.This keyboard is consistent with the distribution of vertical electronic organ keyboard, and wherein one deck keyboard can be a pedalier.

The utility model will be further described below in conjunction with accompanying drawing and embodiment:

Fig. 1 is the arrangenent diagram of the utility model keyboard;

Fig. 2 is the circuit diagram of the utility model embodiment 1.

With reference to accompanying drawing, number in the figure and parts are: keyboard 1, performance button 2.

Embodiment 1:

In the present embodiment, keyboard and 84 bonding electron piano key boards distribute consistent, its internal circuit can with existing standard computer keyboard type seemingly, keyboard can link to each other with computer interface.

As long as change internal circuit, the utility model keyboard just can connect with arbitrary communication interface of existing computer.

For adapting to different consumer demands, keyboard of the present utility model can change its concrete distribution, can be the distribution of 61 electronic organ keyboards, also can change over the 49 simple keyboards distributions that the juvenile uses.Also can be arranged to the multilayer keyboard, consistent with the distribution of vertical electronic organ keyboard.The keyboard number can be by user's the setting that needs, and the change of this keyboard number should be considered as falling into protection domain of the present utility model.
